Audio Player And Audio Recorder in Matlab GUI

I have made Audio Player and Audio recoder in Matlab GUI.

Project is mainly divided into main three section.

  • Audio player
  • Audio recorder
  • Echo generation

Audio player has following features.

  • Load file from  user
  • Save  File with file  duration enter by user.
  • Play
  • Pause
  • Resume
  • Replay
  • Vol+
  • Vol-
  • Speed+
  • Speed-

Audio recoder has following features.

  • Record audio by audio input through microphone
  • Save recording on user desire location
  • Play

Echo generation section include

  • Atten enter by user
  • Dealy enter by user
  • Save

 

 

DETAIL DESCRIPTION:

 project mainly consists of three section.

  • Audio player (section)  load audio  file from the user from any location  and play it.If user select no file then msg is displayed(No file selected). User can also enter the file duration and save it with his desire location and play.First section have following button.
  • Play
  • pause
  • Resume
  • Replay
  • volume up
  • volume down
  • fast forword
  • fast backword

 

  • Second section is the audio recoder which take the audio input from the microphone and save it on user desire location by Save recording button. User have to first set  the recording time (in sec).Recording section have following features.
  • Recording time set by user.
  • start recording
  • stop recording
  • save recording
  • play recording

 

  • Third and last section is Echo Generation section.

Echo signal is the delaye and attenuated version of the sound signal which is added in the original sound wave to produce noise.

This section include following features.

  • Attenenter  by user.
  • Delay enter by user.
  • Save file.

 

Code:

Load file

functionload_Callback(hObject, eventdata, handles)

globalssfs n right_channel p y

 

   [a,b] = uigetfile('*.wav','Select the .wav file to play');

if(a==0)

msgbox('No file selected!!!!')

 

else

file=sprintf('%s',b,a);

 

 [ss,fs,n]=wavread(file);
